What is the classification of fully synthetic 0w20 engine oil?
1 Answers
Fully synthetic engine oils are classified into grades SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, and SN, with the grade increasing in quality sequentially. SN grade is currently the highest level of engine oil. Below is relevant information about fully synthetic engine oil: Definition of fully synthetic engine oil: Fully synthetic engine oil is a high-grade oil product derived from ethylene and propylene dispersed from natural gas or crude oil's gas components. It undergoes complex chemical reactions such as polymerization and catalysis to form a lubricating fluid composed of large molecules. Advantages of fully synthetic engine oil: Fully synthetic engine oil utilizes superior components from crude oil, exhibiting excellent thermal stability, oxidation resistance, and viscosity change resistance, making it significantly superior to mineral and semi-synthetic oils.
